Application led'January 2,1907. -Serial No. 350,361.

To all whom it may concern:

Be it knownthat I, JOHN EDMAN, a citizen of theUnited States, residing at Minneapolis, in the county of Hennepin and State .of Min- Ilesota, have 1invented certain new and useful Improvements-in Grain-Doors for Cars; and I do hereby declare the following to be a full, clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the l Y same. l

My invention has for its object to provide a grain door of improved construction, and to this end it consists of the novel devices and combinations of devices hereinafter described-and defined in the claims.

. In the accompanyin(y drawings which illustrate the invention', like characters indicate ,like parts throughout the several views.

Referring to the drawings, Figure 1 is a view in elevation, showing the central portion of the body of a car t'o which one ofmy improved grain doors is applied. Fig. 2 is a vertical section taken on the line 052 of Fig. 1. Fig. 3 is a horizontal section taken on the line :1:3 ac3 of Fig. 1. Fig. 4 is a horizontal section taken on the line x4 of Fig. 1, some parts being removed. Fig. 5 is a skeleton view infront elevation, showing the grain door locking plates and actuating mechanism therefor. Fig. 6 is a detail in horizontal section on the line of Fig. 1. Fig. 7 is a view corresponding to Fig. 6, but illustrating different positions of the parts. Fig. 8 is a view corresponding to Fig 2, but illustrating -amodiiied construction; and Fig. 9 is a horizontal section taken onthe line w of Fig. S,

some parts being broken away.

The numeral 1 indicates the car body having at its sides the usual door openings formed between door posts 2. the inner edges of' the door posts 2 are stop cleats 3 that extend preferably about half-way up the same. Formed in the door posts 2, outward of the stop cleats 3 and extending from top to bottom thereof, are vertical grooves or seats 4 in which work verti cally extended pivoted lock plates 5 having trunnions 6 at their ends, which trunnions are mounted in suitable bearings 7 at the top and bottom of the door frame. Spur pinions 8 are secured to the upper trunnions 6, and lthese pinions mesh with the outer teeth of Rigidly secured to' racks 9. The racks 9, at their inner ends, have teeth that mesh with the opposite sides of a spur pinion 1() carried by a shortvertical shaft 11 suitably mounted in the top of the door frame, at the center thereof, and provided with an operating lever 12.

The numeral 13 indicates the main section of the grain door, which grain dooris of such width that it will swing between the door posts 2, when the lockplates 5 are turnedventirely into their seats 4, as shownvln Fig. 7. When this grain door is in operative position,

it is tightly pressed against the inner stop cleats 3,\by the lockplates'5, which lock plates are held in the operative positions shown in Figs. 1, 3, 5 and 6, when the lever 12 and racks 9 are in theposition shown in Figs. 4 and 5. By the lock plates 5, the said door 13 may be pressed against the stop cleats 3 under suoli tension that said door can not be moved vertically. The grain door 13 is provided with a folding supplemental section 13l connected tothe upper edge 'thereof by hinges 14. The hinges 14 have a common coupling bolt in the form of a long rod 15, the ends of which project slightly beyond the ends of the grain door and terminate in eyes 16. The eyes 16 work loosely on guide rods 17, the ends of which guide rods are secured to the door posts 2 and to the overlying roof beams 1a of the car. The said guide rods 17 extend vertically nearly to the tops of the door posts 2, are then curved inward and extended horizontally to or approximately to the center of the car, where, as shown, they are anchored by suitable iastenings 1S. The hin ie rod 15, it will thus be seen, is free to late with respect to the hinges 14 and OSCI with respect to both door sections 13 and 13.

On the door 13, near the edges thereof, are lugs or projections 13C that engage with perforations or seats 5 in the lock plates 5, and thereby positively hold said door against upward movements when said lock plates are..

against the main door 13, and the latter, together with the said folded section 13u may.

then be slid upward on the guide rods 17 and secured in the position shown by dotted lines in Fig. 2,the Vree out-turned edge of the said IOO plates 5. It is provided with guide lugs or eyes 2O that work slidably upon curved guide rods 211 located above'the guide rods 17 andsecured to the posts 2 and beams 1a.

l The door sectional?l and 13barepreferably provided with pivotally and slidably mounte'dlock bolts 22 that engage with the inturned clamping plates 5,- to secure the saiddoor sections theret'oagains-t inward movement. g

In practice, the operating leverr12 would preferably' befsecured in .its operative posiend of said lever -`12. With this complete door, and with the seal applied,-the usual outplr or sliding' car door may be dispensed wit In the modification illustratedfin Figs. 8 and 9, the hinge rod 15a, instead of having eyes in its ends, is provided with small spur pinions 16a. These pinions 16a 'mesh with racks 'that extend vertically upward and then curve inward and assume. horizontal positions.' These racks 25 are suitably secured ,to the door posts and are vprovided with flanges 26- that'f'extend. parallel to the teeth of said racks' and engage the extreme endsofthe rod 15?, and thereby hold the pinions'l's in engagement with the said racks, while permitting upward and" down`. ward movements of the grain door; In Fig.

8, thenumeral 2 7 indicates a hookthat is pivotally mounted in the door section 1S- and is engageable lwith av yoke 28onthe door .section v13a to lock the said.. two doorsections together.'

It is, of course, evident that the pressure ofthe grain on the several sections of the door` will be outward and that it-of course `follows that the door section 13 will swing outward under thev pressure of the grain, whenever the lock plates 5 are moved into their inopfrom the card andathus makes it unnecessary l 1. rPhe combination with a oar body havy ing stop cleats .and pivotedlock plates ap- `plied to the sides of its door opening, 'of' vla'4 lower grain door section adapted to be moved laterally through said door opening and to be clampedbetween'said plates and co-o er ating stop olea-ts,ijguides tor said' grain oor'Y extending upward along the sides of the door opening. and thence curving inward and extending approximately to the center of the l l car, whereby said' door `may have a. sliding movement, and an upper grain door'section mounted for sliding movement on independ-"- ent guides, substantially as described. i

'2. The combination with -a car body hav? 'A ing stop cleats and pivoted lock plates applied to the sides of its kdoor opening,v of a lower grain door sectionv ladapted to" be moved laterally through said door openingand to be clamped between said plates and co-operating stop cleats, guides for said grain ldoor extending upwardalong the sides of the door opening-and thence curving in ward and extending approximately to the center of the car, whereby said door may have a sliding movement, an upper grain door section mounted for sliding movement'. 9

on independent guides and also adapted'to be moved laterally through said door opening, and locking means for securing said up- "f f per'door section when `in closed position to the pivoted lock plates, substantially as de- L scribed. f

3. The Ycombination with a car, of a grain door seated in the door opening thereof, and

-pivoted lock and closure plates mounted on the sides of the "door frame and engageableA v *with the edges of said-grain door, the said door and lock plates havinginterlocking parts which positively hold the door against IOC vertical movement when such lock plates are y in operative position, the same consisting of i a stud or prolection on one of the members and a perforation or recess-in the. other member which interlock upon -the swinging l. l

merelyl ofthe lock plates.
